Another obiect of this'invention is to pro-i vide a .device which may beeasily attached to the present vheadlights of motor. vehicles withoutalteration in the body or caslngv of the lamp.` u o A further object ,ofthis invention is'to Yprovide a device which is easily and readlly:..djustable sothat a motor vehlcle moving from onejurisdiction toanother. where different headli ,ht laws are in existence may have thehea lights quickly adjusted to con.

.form to the laws of the particular jurisdiction. U

)A still further. object of this invention 1s to provide an anti-glareheadlight which will adequately illuminate the roadway, but which willnotl project a beamof light beyond a predetermined point in advance ofthe vehicle, nor above a predetermined height.

A further object of this invention is to provide a device of thischaracter which'is symmetrical in design and when installed on a motorvehicle will add to rather than detract from the artistic outlines of'the' vehicle, the devicepresenting the appear'- ance of a slightlyelongated lamp 'which may `he varied in size to conform to theproportions pcesented by the vehicle.

housing 10, and at its inner end abutts the the following detailedAdescription thereof,

wherein: y, Fig. 1 is a transverse section of a device. constructedaccording to this invention .taken substantially through the centerthereof, and

Fig'. 2 is a transverse :section of the device 'taken substantially online 2-2 of Fig. 1.

Referring to the drawings, aJnd first to .Y Fig. `'1, 10 designates alamp housingor casingof the conventional type in resent use having areflector 11 mounted t erewithin. 60 A 'lamp 'socket 12 is .adapted toproject through the casing 10 and the reilector X1,- `and a lamp 13 isadapted to fit into said socket 12 at its inner end, so that the lamp'when lighted vwillhave its rays or beams projected outwardly bysaidreflector 11 n outer casing'or housing '14' is adapted to fit into theouter end of the inner or nain outer end of said reflector, so that whenthe casing 14 .is bolted, riveted or otherwise firmly secured to saidcasing 10, the inner 4end of said casing 14 holds the reiector 11 in'adjusted position. the casing 14 there is secured a, plate 15 which hasan opening 16 therein to allow the light beams projected by Isaidreector 11 to pass therethrough. Abutting the outerj'surface of theplate' 15 is a lens 17 which is preferably of the saw-toothed type', 90and the lens 17 is adapted'to be held in position by a ring 18'whichprojects over. the outer Asurface ofsaid lens 17. Thev ring A18 may hedetachahl'y held in position by screws- 19 or the like aothat should the5,5.' lens 17 becomes broken, it may be easily sides to thedeiector 20and project outwerdly through thev casing 1li so that the deflector 20may he swung to any desired an le or inclination. The outer ends of the95. ms 21 are preferably threaded to receive a At the outer end of thedelector has a groove' 24 across the inner edge thereof to detachablyreceive a lens which is preferably of the sawtoothed type,` and the `topof the deilector 20 has a ridge 26 across the inner edge thereof spacedinwardly sufficient to form a seat for the upper edge of the lens 25. A.strap spring 27 is secured to the u per side of the top 28 of thedeflector, an 1s pref erably held in position b screws 29, or the like.The inner end of t ie spring 27 overhangs the inner edge of the top 28and projects downwardly sufliciently to engage the upper edge of thelens 2 5 so as to hold the same firmly against the ridge 26.

Within the delector 20 are secured a plurality of deflector plates 3()which are held in spaced relation to eaf'li other and are secured in theopposite sides of the deflector 2 0. The upper surface vof the deflector'plates 30. is preferably of. non-reflecting ma terial, and to answerthis purpose niajy be painted or enameled black or the like. The lowersurface ofthe deilector plates 30 is preferably polished or the like soas to form an'e'liicient reflecting surface. The plates 30 adjacentthebottom of the deflector 2() may be substantially parallel to thebottom,

but the succeeding plates are inclined for- -Wardly, the angle ofinclination gradually becoming greaterwith each plate, and with theincreased inclination of'the plates the spaces therebetween is'succeedingly diminished.

The beams of light which are projected forwardly by the reflector 11strike the lens 25.as at 31. l The beam is vthen projected into thedelector 20, striking the upper surface of the plateA 30 atapproximately 32. The upper surface of the plate 30 being ofnon-reflecting material has the tendency to deaden the beam of lightwhich is projected on to the lens 17 at the point 33, and from thispoint the light is piojeeted along the line 84.' In a similar way a beamof light being projected from point on the refiector 11 strikes the lens25 at point 36 and is projected straight through the lens into thedeilector. 20, strikingr the. lower side of plate 30 at point 37. Frompoint 23-7 the beam of-.ligh-t is projected without any decrease in itsintensity through the lens 17 along the line 38 which' is substantiallyparallel to the line 34. j

i 'The lines 34 :md it. which indicate the angle ol inclination of thebeams of light projected from the reflector 1l' may lbe varied byswinging .the deflector upon its axis 2l.- Inl order to accoii'iplislithis adjustment a lug 39 is secured to the bottom of the deflector 20and projects down wardly therefrom. A slidable plate 40 is positioned onthe inner surface of the casing 1 4-, and overlaps an opening sllin` thecasing 1-1 which is large enough 'to slidably receive a bolt 42 or thelike'wliich is secured to the plate 40 and projects downwardlytherefrom. A second upstanding lugr 43 is secured to the inner side ofthe plate 10, and a link 44 is pivotally secured at one 'end to the lug4-3 and at the opposite end to lug 39 by riiw'ets 45 or the like.' Themovement either forward or backward `of thebolt 42 thus rocks thedelector upon its aX'is 21 causing the beams of light to be projectedeither downwardly or upwardly. When-the desired inclination of thedeiect'or is found a nut 46 is tightened on the bolt 42, which pre ventsany movement of the bolt 42 in the slot or opening 41. A will be seenfrom the disclosure, 'this adjustment of the de- `Hector may be effectedwithout removing any of the component parts of the lamp, as it is simplynecessary to loosen the nut 4:6 which is ,on the outer side of thecasing 14 and then by moving the bolt either forward or baclrward thedesired inclination of the light beams may be obtained.

t is of course understood that various changes and modifications may bemade in the details of `'construction and design of the abovespecifically described embodiment of the invention without departingfrom the spirit thereof, such changes and modications being restrictedonly by the scope of the following claims:
